Find the equations of the tangent lines to the graph of the equation below that are parallel to the line given.

Question

f(x) = (x + 1)/(x − 1)

2y + x = 6

y = 

 y = 

 

Then graph the function and the tangent lines.

Answer 1

What is the slope of the line 2y + x = 6?

Which graph has parallel lines with the same slope?
